Conglomerate rocks are sedimentary rocks. They are made up of large sediments like sand and pebbles. The sediment is so large that pressure alone cannot hold the rock together; it is also cemented together with dissolved minerals.Conglomerate is often much harder and resistant than the sandstones and shale that surround it. Conglomerate is scientifically valuable because the individual stones are samples of the older rocks that were exposed as it was forming—important clues about the ancient environment.
